COMPREHENSIVE DESIGN OF A LOW ORBIT SATELLITE NAVIGATION SYSTEM

Whille GPS was in its infancy:

Design and development of navigation satellite concepts and alternatives. This is a comprehensive study of alternatives to the military system. The new system should be cost effective for commercial and general aviation. Developed new wave-form concepts and satellite constellations, which, when combined with modern estimation techniques, have the potential of providing adequate navigation to civil users at a fraction of the cost of the military system. Evaluated system accuracy, and availability. An article in The Journal of the Institute of Navigation entitled, "Low Orbit Navigation Concepts" was published in the Fall '88 issue.
